SCIMA: A Novel Processor Architecture for High Performance Computing

摘要

Clock acceleration and ILP extraction have drastical-ly improved processor performance. However, perfor-mance of memory has not been improved so much as that of processor, thus the problem of performance gap between memory and processor, which is called memory wall problem, is becoming very serious. This will get more serious in the near future. We propose a new VLSI architecture which can solve this problem. Our architecture integrates software-controllable memory into the processor chip. We have evaluated our architecture on Linpack benchmark and QCD simulation. These results indicate that our proces-sor achieves high performance by using On-Chip Mem-oory effectively.
